NURSING BOTTLE.

Application filed March 31, 1923. Serial No. 629,159.

T 0 all 207mm it may concern:

Be it known that I, J OSEPHI CARL VVANGEN, a citizen of the United States, residing at Great Falls, in the county of Cascade and State of Montana, have invented a new and useful Nursing Bottle, of which the following is a specification.

This invention relates to nursing bottles, and has for one of its objects to provide a bottle of this type in which the nipple is more effectively secured to the bottle itself, thereby preventing leakage and any unintentional detachment of the nipple from the bottle with the consequent spilling of the contents.

A further object of the invention is to provide a nursing bottle in which the nipple may be readily attached to and detached from the bottle, and which will be securely held in such a position as to prevent the stretching of the nipple, with the consequent deterioration of the same.

With the above and other objects in view, which will appear as the description proceeds. the invention consists in the novel details of construction and combinations of parts, more fully hereinafter disclosed, and particularly pointed out in the appended claims.

Referring to the accompanying drawing, forming a part of the specification, in which the figure is a side elevational view. partly broken away of a bottle constructed in accordance with the present invention.

Referring to the drawing in detail, 10 de notes the body portion of a bottle constructed of any suitable material, preferably glass, and which may be cylindrical or polygonal in contour. The body portion 10, at its forward end, is provided with a neck 10' and said neck is annular in contour and of substantial thickness, and further is inset with respect to and of greater thickness than the thickness of the body portion 10. The thick ness of the neck 10 is such as to provide a substantially wide forward end edge 10" which constitutes a seat for a nipple to be presently referred to. The outer periphery of the neck 10 is formed with threads 11 with which engage the interior threads 13 of an annular locking collar or ring 12 provided at its top with an inwardly extending flange 18.

The edge 10 of the neck is provided centrally thereof with an annular semi-circular groove 14, which is adapted to receive the annular head 15, provided tipon the inner end of a nipple 16, which nipple may be formed of resilient material, such as rubber, as is well known. The inner end of the nipple is also provided with an outwardly projecting annular flange 17 which is adapted to be engaged by the inwardly projecting flange 18 of the ring 12, to securely clamp the nipple in position over the mouth of the bottle, as will be readily understood.

The inner diameter of the nipple 16, at its inner end, is the same as'the diameter of the mouth of the bottle, whereby when the nipple is mounted in position with respect to the bottle, the inner face of the nipple will be flush with and form a continuation of the inner face of the neck, under such conditions providing for an uninterrupted discharge from the mouth of the bottle into the nipple and prevent any of the contents of the bottle passing around the forwardend edge 10" of the neck and lodging against the outer face of the neck.

The parts are so constructed and assembled that the inner edge of the flange 18 of ring 12, is so positioned relative to the head 15 and groove 14, as to force the said bead firmly into the groove, to the end that an efficient liquid-tight joint may be secured. Furthermore, this bead and groove construction assists in maintaining the nipple in shape and prevents the unintentional displacement of the nipple from the mouth of the bottle by the infant, with the consequent spilling of the contents of the bottle.

The construction is such that the parts may be readily disassembled by unscrewing the ring 12 and removing the nipple 16 for the purpose of cleansing, sterilizing, and filling the bottle. whereupon they may be readily re-assembled by replacing the nipple and ring 12 to the position shown.

If desired, the side wall of the bottle may be provided with suitable indications 20, for the purpose of readily showing the cubical contentsof the bottle.

Having thus described the invention, what I claim and desire to secure by Letters Patent of the United States is:

1. A nursing bottle comprising a body portion provided with a peripherally threaded neck having a substantially wide plane forward end edge provided with an annular groove, a resilient nipple having a plane inner end edge seating entirely on the forward end edge of the neck and formed by the inner face of the nipple at its inner end will form a continuation of the inner face of the neck, and a locking collar en gaging directly with the threads of the neck and having means opposing the forward end edge of the neck and engaging the nipple for securing it to the bottle and further providing in connection with said bead a liquid tight joint between the innerend edge of the nipple and the forward end edge of the neck.

' portion provided ing means opposing the forward end sedge 2. A nursing bottle comprising a body with a peripherally threaded neck havinga substantially wide plane forward end edge provided with an annular groove, a resilient nipple having a plane inner end edge seating entirely on the forward end edge of the neck and formed with a bead extending into said groove to prevent lateral shifting of the nipple relative to the neck, the inner diameter of said nipple at its inner end edge being the same as the inner diameter of said neck, whereby the inner face of the nipple at its inner end will form a continuation of the inner face of the neck, a locking collar engaging directly with the threads of the neck and havofthe neckand engaging th'e nipple for securing it to the bottle and further providing in connection with said bead a liquid tight joint between the inner end edge of the nipple and the forward end edge of the neck,

a and said neck being inset with respect to said body portion.

3. A nursing bottle comprising a body portion formed at one end with a periphery threaded neck having a substantially wide plane forward end edge provided with an annular groove, a resilient nipple having an outwardly extending flange and a bead at its inner end, said nipple having-its inner end edge seating entirely on the forward end edge of the neck and a plane bead extended into said groove to prevent lateral shifting of the nipple relative to the neck, the inner diameter of said nipple at its inner end edge being the same as the inner diameter of the neck whereby the inner face of the nipple at its inner end will form a continuation of the inner face of the neck, and an interiorly threaded locking collar engaging directly with the threads of the neck and formed with an inwardly extended flange engaging the flange of the nipple for securing the latter to the bottle and further in connection with said bead providin a liquid tight joint between the inner end e ge of the nipple and the forward end edge of the neck. v

4. A nursing bottle comprising a body portion formed at one end with a peripherally threaded neck having a' substantially wide plane forward end edge provided with an annular groove, a resilient nipple having an outwardly extending flange and a bead at its inner end, said nipple having a plane inner end edge seating entirely on the forward end edge of the neck and its bead extended into said groove to prevent lateral shifting of the nipple relative to the neck, the inner diameter of said nipple at its inner end edge being the same as the inner diameter of the neck whereby the inner face of the nipple at its inner end will form a continuation of the inner face of the neck, an interiorly threaded locking collar engaging directly with the threads of the neck and formed with an inwardly extended flange engaging the flange of the nipple for securing the latter to the bottle and further in connection with said bead providing a liquid tight joint between the inner end edge of the nipple and the forward end edge of the neck, and said neck being inset with respect to said body portion.

5. A nursing bottle comprising a body portion provided with a'neck peripherally threaded throughout, said neck having a substantially wide plane forward end edge provided with'an annular groove semi-circular in cross section, a resilient nipple having a plane inner end edge seating entirely on the forward end edge of the neck and formed centrally thereof with an annular bead, said head semi-circular in cross sec tion and extending into and snugly fittin said groove to prevent lateral shifting of the nipple relative to the neck, the inner diameter of said nipple at its inner end edge being the same as the inner diameter of said neck whereby the inner face of the nipple at its inner end will form a continuation of the inner face of the neck, and a locking collar engaging directly with the threads of the neck and having inwardly extending means opposing the forwardend edge of the neck, said means engaging the nipple for securing it to the bottle and further providing in connection with said bead and groove a'liquid tight joint between the inner end edge of the nipple and the forward end edge of the neck.
